Lifetime Stone Guarantee

We are so confident in our patented technology and heirloom quality of our Nexus Diamond™ alternative that we guarantee our stones for life! With normal wear and proper care, your Nexus Diamond alternative will not chip, crack or discolor. If there is ever a problem with your Nexus Diamond alternative, we’ll replace the stone for free. Period.

Sourcing only the finest quality Moissanite comes with its advantages! Rest assured your Moissanite stones will not only last a lifetime, they will also maintain their superior brilliance, fire and sparkle! Should any issue arise with your white or colored Moissanite gemstones, we’ll simply replace them for free. Forever.

We are proud to offer our customers the highest quality lab grown diamonds on the market! Our lab grown diamonds will perform identically to mined diamonds, and with proper care, will last many lifetimes. To protect your lab diamonds and jewelry from accidental damage and loss, we highly recommend purchasing an Extend Protection Plan (kindly review details in the Extend section below).
If you are in need of repair, please contact us anytime! You may send your jewelry to us so that we evaluate your jewelry piece.

Some limitations apply. Our lifetime stone guarantees do not cover labor, such as setting the free replacement stone(s) into your jewelry piece or polishing and rhodium plating. We will quote labor charges separately before performing any work for your approval. Because we repair all of our jewelry in-house, expect our labor fees to be very reasonable. Guarantees do not include lost or missing stones or other color gemstones. Of course, we’re happy to replace a lost or missing stone or color gemstone at a reduced cost for both the stone(s) and labor. Any repair or service performed by a jeweler other than Diamond Nexus voids all stone guarantees. Warranty of jewelry metal and components are covered separately and described in the Free Lifetime Manufacturing Warranty section below.

Free Lifetime Manufacturing Warranty

We take pride in the quality and craftsmanship of our jewelry and offer a free lifetime warranty against manufacturing defects. Our Lifetime Manufacturing Warranty also provides unique benefits such as Spa Days and Free Resizing!

If you experience damage to your purchase due to manufacturing, we recommend you contact us so we may evaluate your piece. You may send your jewelry to us so that we perform the evaluation. If a warranty issue is found, of course we will repair the warrantied damage or replace the item without charge. For repairs that are not covered under the lifetime warranty, we will quote a repair price for your approval before any work is performed.

Your two free Spa Days include a thorough inspection of your jewelry along with a deep cleaning, polishing and rhodium plating (white gold only). Spa Days also include free shipping both ways within the U.S. and Canada. You may take advantage of your Spa Days at your discretion within the first year!

We offer one complimentary resizing within one year of purchase date for our standard ring styles sizes 4-10. Please note that while our eternity rings cannot be resized, they may be exchanged within one year for any standard size; an additional charge may apply for a larger size exchange and a credit will be offered for a smaller size exchange. All of our rings are offered, or may be resized to, non-standard sizes for an additional fee. Free Resizing excludes clearance items.

Some limitations apply. Please note that all fine jewelry may be affected by normal or excessive wear, especially for rings, since they tend to incur the most wear and tear. Our manufacturing warranty excludes coverage for wear and tear, loss of gemstones, product loss, or theft. Warranty excludes damage or loss caused by a failure to obtain the repairs required to preserve the integrity of the jewelry. Warranty is void if another jeweler works on the item. Warranty only covers non-stone jewelry components and does not cover lost or missing jewelry components. If components are missing, repairs may incur a cost for replacement. Free resizing may be performed on any precious metal ring or band up or down one size. Size adjustments greater than one size may incur an additional charge. Non-precious metal such as Tungsten and Titanium cannot be resized, but may be replaced for the correct size and may incur an additional charge; please contact us for assistance. Clearance items are excluded from Warranty. For additional jewelry coverage and enhanced benefits not covered by this Warranty, please consider purchasing an Extend Protection plan, described below.
